Most of the vestages of the Circque stuff is gone thankfullly, I don't see a problem with them upgrading the M class ships, remember that no ship much bigger than the M class ships goes to Alaska so the need is there.

One of the more interesting points in this press release is what is not said. There is no mention of Mercury or Century. I personally think their days are numbered with Celebrity with Merucry going as early as next year..
